Hi,
I had a look into the code.
The PndTrack flag can be filled both in PndRecoKalmanFit and in PndGenfitAdapters, with the following values:
i) -10 if pz=1e-9
ii) -2 if the conversion from GenfitTrack to PndTrack has failed
iii) -1 if the the number of degrees of freedom (NDF) = 0
iv) 1 if NDF != 0

Concerning fStatusFlag, it's a data member of GFAbsTrackRep. I see that in GFKalman it is set to 1 if you catch an exception in processHits(); then there is a continue and you go to the next rep.

So if I understand correctly, the values of these two flags do not seem to be related. Or am I wrong?

Susanna
